I think with the system they are demoing for communication that is true. They seem to use non directional transmitters of about 5W which cover an area of 'four or five blocks' ( http://www.youtube.com/watch?v=5bO0tjAdOIw&list=PLbOnG9yNO5u... ) A system for transmitting power, which I don't think they have built on any scale, you'd probably want to focus a beam towards the receiver with the power loss being proportional to the amount the beam spreads out. |
